The HyTRON system requires none of the safety circuits and performance limiting circuitry which lithium ion requires to operate safely. HyTRON 140 employs exclusive high performance cells capable of delivering superior performance in any high current application. Ideally suited for powering the latest generation of high definition equipment the HyTRON 140 can also provide extended runtimes of up to 6 hours on DVC format camcorders. Because of its highpower, and unlike lithium ion batteries, it does not require limiting when operating limiting when operating both a camera and on-camera UltrLight up to 85watts (up to 175 watts total power). The HYTRON 120 is the perfect All Morning/All Afternoon battery. Because of its advanced performance characteristics, HyTRON 120 is the only new technology in the industry to carry the 3 year MAXX Guarantee. The HyTRON 50 is particularly well suited for fast paced handheld operations, with on-camera lighting (up to 25 watts), taking advantage of its extremely small size, light weight, and long runtime. Its 14.4 volt design optimizes performance in all environments. The HyTRON 50 is the perfect battery for professionals who are primarily concerned with the "economical performance insmallest package" benefit of new cell chemistries. on for every type of video operation. No single battery size, type or chemistry can offer the ultimate in all of these characteristics in every shooting situation for every type of video operation. That's why Anton/Bauer employs all three major chemistries - nickel metal hydride, lithium ion, and nickel cadmium. The entire range of price, size and capabilities of Anton/Bauer Logic Series andInterActive batteries can be mixed and matched on the same InterActive charger. The right battery is an Anton/Bauer system that allows you to work the way you need to, with unmatched features, performance, service life and value. Only Anton/Bauer Digital batteries communicate directly with every Anton/Bauer InterActive Charger. Digital batteries also communicate directly with the InterActive viewfinder of current professional camcorders. No modification or special adaptors are necessary - the feature is standard equipment with the camera. Available only from Anton/Bauer, this unique on board display provides the battery feature most requested by videographers today - both full-time analog fuel gauge and a remaining time indication available simultaneously. No set-up is required and the battery can be used on any piece of portable equipment. The RealTime display simultaneously provides remaining runtime indication along with an analog fuel gauge indication in the battery on-board LCD.
